Abstract (en)

The present invention relates to a crosstalk estimation device for estimating crosstalk between disturber communication lines and victim communication lines. The crosstalk estimation device is able to change the power spectral density PSD on the victim communication lines and/or the disturber communication lines. The crosstalk estimation device further receives measured changes in operational parameters on the victim communication lines and/or disturber communication lines in order to estimate the crosstalk induced in the victim communication lines and/or disturber communication lines.
